Actually, I think both of these statements are 100% correct in the patch.
> "`k` is a nonnegative number."
Here, we are talking about exponents which are allowed to be zero, so this
is correct.
> "assumed to be a positive integer possessing a primitive root"
This is also correct because PARI's behaviour for negative arguments to
`znprimroot()` is undocumented, so we cannot rely on it (in practice, it
does work though).
